Pulmonary function in neuromuscular diseases.

Lung function were determined in patients with neuromuscular diseases. The decrease of TLC, VC and the increase of RV were established. The ratio FEV1/VC was decreased during two months after the onset of disease in patients with acute polyradiculoneuritis and during one year after the onset of the respiratory insufficiency in patients with myasthenia gravis. These data have the practice importance for establishing of the period of artificial ventilation. Its theoretical significance is that they supply the knowledge deficit in clinical physiology of respiration in some neurological diseases.
